is there an ext to keep notes per page?

[Offset]

As an example, let's say I wanted to keep a note for a news site page that says "this is related to story at example.com/whatever". I go to a DIY fixit page and make a note that "I tried mineral spirits and it didn't work" and that note can refresh my memory years later.

Is there such an ext for PM? Thanks.

You can add a description for a bookmark.
